TMP member Deathwing is working on a post-apocalyptic ruleset, and my local club volunteered to playtest it for him. It worked out pretty well! You can tell this thing is very close to a commercial release. Not too many gaping holes in the rules, etc. Here's our first playtest report: link

The game mechanics sound very interesting. Really like the activation sequencing, and the idea of shooting effects being indeterminate for a brief span is really neat. Bet people agonize about whether to overkill or not.
